Preface Polymer electrolyte fuel cells (PEFCs) or proton exchange membrane fuel cells (PEMFCs) have been suggested as alternatives to replace many existing energy conversion technologies, including internal combustion engines and batteries. The most significant advances in PEFC technology achieved in the last decade have occurred in areas related to automotive applications, namely coldstart capabilities, enhanced durability and better understanding of water management and mass transport losses. This volume of Modern Aspects of Electrochemistry is intended to provide an overview of advancements in experimental diagnostics and modeling of polymer electrolyte fuel cells. Chapters by Huang and Reifsnider and Gu et al. provide an in-depth review of the durab
